Mmene Mafilimu Amagwiritsira Ntchito Amakhudza Khalidwe ndi Maonekedwe Abwino
Pakanema kanema, chithunzi kapena nyimbo zikusungidwa mu fayilo ya digito zotsatira zingakhale fayilo yaikulu yomwe ndi yovuta kuyendayenda ndipo imagwiritsa ntchito kukumbukira kwambiri pa kompyuta kapena hard drive komwe imasungidwa. Choncho, mafayilo amaumirizidwa - kapena apangidwa ang'ono - pochotsa zina mwa deta. Izi zimatchedwa "lossy" compression.
Zotsatira za Kupsinjika
Kawirikawiri, zovuta zowerengeka (algorithm) zimagwiritsidwa ntchito kotero kuti zotsatira za deta yotayika sizimasowa diso pavidiyo ndi zithunzi, kapena sizikumveka mu nyimbo. Zina mwaziwonetsero zomwe zatayika zimapindula ndi diso laumunthu lomwe silingathe kupanga kusiyana kochepa kwa mtundu.
Mwa kuyankhula kwina, ndi teknoloji yabwino yothandizira, simuyenera kuzindikira kuperewera kwa chithunzi kapena khalidwe labwino. Koma, ngati fayilo iyenera kuumirizidwa kuti ikhale yaying'ono kwambiri kusiyana ndi mawonekedwe ake apachiyambi, zotsatira zake zingakhale zosatheka koma zingathe kupangitsa kuti chithunzichi chikhale choipa kwambiri kuti vidiyoyo isadziŵike kapena nyimboyo ndi yopanda pake komanso yopanda moyo.
Mafilimu otanthauzira apamwamba angatengere kukumbukira zambiri - nthawizina zoposa 4 gigabytes. Ngati mukufuna kusewera kanema pa foni yamakono, muyenera kupanga fayilo yaing'ono kwambiri kapena ingatenge makalata onse a foni. Kutayika kwa deta kuchokera kupsyinjika yapamwamba sikuwonekeratu pawindo la inchi inayi.
Koma, ngati mukufuna kufalitsa fayilo ku Apple TV, Roku Box, kapena chipangizo chomwecho , chomwe chikugwirizanitsidwa ndi TV yayikulu ya pawindo, kupanikizika sikudzangowonekera, koma kudzachititsa kuti vidiyoyi ikhale yovuta komanso yovuta yang'anani. Makomera angawoneke osasangalatsa. Mphepete ikhoza kukhala yowopsya ndi yokhotakhota. Zosuntha zingasokoneze kapena kusinthasintha. Ichi ndi vuto pogwiritsa ntchito AirPlay ku iPhone kapena iPad. AirPlay sikungosuntha kuchokera ku gwero. M'malo mwake, ikukhamukira kusewera pa foni. Kuyesera koyamba ku AirPlay kawirikawiri kunayambitsidwa ndi zotsatira za mafilimu apamwamba.
Zosankha Zokakamiza - Quality vs Saving Space
Pamene mukuyenera kulingalira za kukula kwa fayilo, muyenera kuiganizira ndi kusunga khalidwe la nyimbo, zithunzi kapena kanema. Danga lanu lolimba kapena malo osindikizira adiresi angakhale ochepa, koma ma drive akuyenda kunja akutsika mtengo wa zikuluzikulu. Zosankha zingakhale zogwirizana ndi khalidwe. Mukhoza kupeza maofesi ambirimbiri ophatikizidwa pa hard drive 500 GB , koma mungasankhe kukhala ndi mafayilo apamwamba okha.
Mukhoza kusankha zofuna zanu pazomwe ndalama zolembedwera kapena zosungidwa zimakanikizidwa. Nthaŵi zambiri zimakhala zosungira nyimbo monga iTunes zomwe zimakulolani kuti muyambe kuyimba nyimbo zomwe mumazilembera. Nyimbo zopanga nyimbo zimalimbikitsa kwambiri kuti musataye zina mwazinthu za nyimbo - 256 kbps kwa stereo pamasewero - HiRes mafilimu mafilimu kuti alole zambiri apamwamba ndalama. Zithunzi za jpeg zoyenera ziyenera kukhazikitsidwa kuti zikhale zazikulu kukula kuti zikhale ndi khalidwe la zithunzi. Mafilimu otanthauzira apamwamba ayenera kusindikizidwa mu mawonekedwe awo oyambirira a digito monga h.264, kapena MPEG-4.
Cholinga ndi kupanikizika ndiko kupeza fayilo yaying'ono popanda kutaya chithunzi ndi / kapena deta yolondola kuti ioneke. Simungapite molakwika ndi mafayilo akuluakulu komanso osakanikirana kupatula ngati mutataya malo.
